History

Graziano Trasmissioni was started in 1951 as a small family company with 15 employees by Carlo Graziano. In 1963, the company moved to its present headquarters in Cascine Vica. After 1981, the company's export activity increased progressively. The company then expanded, opening a factory in India in 1999, another in Suzhou (China) in 2006 and a third in Cerveny Kostelec (Czech Republic), in 2006.

In 2007 it merged with North American Fairfield, becoming Oerlikon Drive Systems, part of the Oerlikon Group.

From 1996-1997, starts the cooperation with Ferrari, it developed and supplied the complete gearboxes for the Ferrari 360, 612 Scaglietti, Enzo, F430, 575M Maranello.

The new Lamborghini Aventador uses a single-clutch lightweight 7-speed semi-automatic gearbox built by Graziano. .[7][8] Despite being single-clutch, gear-shifts are accomplished in 50ms. The Gallardo and the first-generation Audi R8 used a mid-engine Graziano gearbox (manual or automated manual versions).

The DCT gearbox used in the new Audi R8 was developed in partnership with Graziano. It is built and pretested at Graziano's Luserna plant in Italy before shipment to Volkswagen's Kassel plant in Germany, where the clutch and mechatronics modules are added. The finished transmission is then sent to Audi.[9]

The Aston Martin One-77, Vantage S, V8 Vantage, Aston Martin DB9 and Maserati GranTurismo S use rear transaxle gearboxes while the Maserati Quattroporte and Coupé & Spyder Trofeo- GranSport had an MT-AMT (Automated Manual) gearboxes.

The 2014 McLaren 650S uses the second generation of the SSG, with revised software which improves shifting times by further 0.3s[10]

Alfa Romeo 156

The Alfa Romeo 156 (Type 932) is a compact executive car produced by the Italian automobile manufacturer Alfa Romeo. This range of vehicles were manufactured between 1996 and 2007 while the 156 saloon was discontinued in Europe late in 2005, leaving the Q4 Crosswagon to continue in production until the end of 2007.Introduced at the 1997 Frankfurt Motor Show as the replacement for the Alfa Romeo 155 the 156 was well accepted and in the following year went on to win the 1998 European Car of the Year awardCars were assembled at the Fiat Group factory in Pomigliano d'Arco, Italy and at a General Motors facility in Rayong, Thailand. Production in Thailand began in March 2002 and ran for only a couple of years and vehicles produced there were targeted for the Asia Pacific markets). Between 1997 and 2005, approximately 680,000 vehicles designated 156s were produced.The 156 was available in saloon, Sportwagon estate and Crosswagon crossover bodystyles with seven engine configurations; it went through two facelifts, first in 2002 and then in 2003. The Sportwagon

advertising campaign was made with actress Catherine Zeta-Jones.In 2007 the 159 became the replacement for the 156. This replacement vehicle went on to also spawn the Brera, the three-door coupe that replaces the Alfa Romeo GTV along with its convertible sister the new Spider.

Aston Martin DB9

The Aston Martin DB9 is a British grand tourer first shown by Aston Martin at the 2003 Frankfurt Auto Show. Available both in coupé and a convertible bodystyles, the latter being known as the Volante, the DB9 was the successor of the DB7. It was the first model built at Aston Martin's Gaydon facility.

The DB9 was originally designed by Henrik Fisker, has an aluminium construction. The chassis is the Ford developed VH platform whilst the engine is the 5.9-litre V12 from the Vanquish. The 2013 model year facelift saw many improvements to the design, the engine and the overall driving experience.

The DB9 is rated well by car critics, who appreciate the car's interior and exterior design. In spite of comments regarding the DB9's poor handling, reviewers liked the car's ride and driving experience. Some also held issue with the DB9's small rear seats, cargo space and poor satnav.

Aston Martin Racing adapted the DB9 for sports car racing, producing the DBR9 for FIA GT1 and the DBRS9 for FIA GT3. These two cars are modified DB9 models adapted for motorsport; the interior features are removed and the aluminium body panels are replaced by carbon fibre panels. Additionally, the engine has been tweaked in both the cars to produce more horsepower and torque.

Production of the DB9 ended after 12 years in 2016, having been replaced by the DB11 which uses an all-new platform and engine.

McLaren 570S

The McLaren 570S is a sports car designed and manufactured by British car manufacturer McLaren Automotive. It was unveiled at the 2015 New York International Auto Show. McLaren predicts that the model will help triple the company's sales volume by 2020,

McLaren P1

The McLaren P1 is a limited-production plug-in hybrid sports car produced by British automobile manufacturer McLaren Automotive. Debuted at the 2012 Paris Motor Show, sales of the P1 began in the UK in October 2013 and all 375 units were sold out by November. Production ended in early December 2015. The United States accounted for 34% of the units and Europe for 26%.It is considered by the automotive press to be the successor to the F1, utilising hybrid power and Formula 1 technology, but does not have the same three-seat layout. It was later confirmed that the Speedtail served as the actual successor to the F1. Like the F1, the P1 has a mid-engine, rear wheel drive design that used a carbon fibre monocoque and roof structure safety cage concept called MonoCage, which is a development of the MonoCell first used in the MP4-12C and then in subsequent models. Its main competitors were the LaFerrari and the Porsche 918. They are all similar in specifications and performance, and in a race around Silverstone circuit they were all within half a second of each other, the P1 finishing first at 58.24 seconds and the LaFerrari finishing last at 58.58 seconds; the 918 was in-between with 58.46 seconds.58 units of the track oriented P1 GTR and 5 units of its road legal counterpart, the P1 LM were produced after the initial run of 375 cars.

13 eXperimental Prototype 'XP', 5 Validation Prototypes 'VP' and 3 Pre-Production 'PP' cars were produced by McLaren before the production of the P1 started, a number of which have been refurbished, modified and sold to customers.

Saurer

Adolph Saurer AG was a Swiss manufacturer of trucks and buses under the Saurer and Berna (beginning in 1929) brand names. Based in Arbon, Switzerland, the firm was active between 1903 and 1982. Their vehicles were widely used across mainland Europe, particularly in the interwar period.

Selespeed

Selespeed is the name of an electrohydraulic manual transmission used in Alfa Romeo cars, developed by Italian company Magneti Marelli and made by Graziano Trasmissioni.The Selespeed is a robotized manual gearbox with electronic clutch. In its current incarnation it can be operated via paddle shifters from the steering wheel or via a "joystick" like a sequential manual gearbox. The right-hand paddle shifter shifts upwards and the left side downwards. The gearbox also has a city-mode which self-shifts in a manner similar to a traditional automatic gearbox.

Selespeed was first introduced in 1999 in the Alfa Romeo 156. At that time it was the first car in its class with such a robotized gearbox. This first version had buttons on the steering wheel for changing gear. With the facelift of the 156 in 2002 these buttons were replaced by paddle shifters (first seen in the Alfa Romeo 147) due to a new steering wheel design.

During normal driving it is possible to use either the paddles or the joystick but if the driver tries to use paddles during joystick mode the joystick has higher priority. The speed of the gear change depends on the engine revs, if the engine has more than 5000 rpm and the throttle is pressed more than 60% the change is faster. The system also has a rev limiter to avoid over revving, (in GTA models this behaviour is removed). Downshift are accompanied with automatic rev-matching. This gearbox is made for sportive driving but the city-mode allows using it like an automatic gearbox in city driving.
